AUTOMATIC DIST'RIBUTER FOR bWER-SEPARATOERS;

Specification of Letters Patent.

Patented March 27, 1906.

To all whom it may concern:

Be it known that we, GEORGE GEISENDOR- I FER and WILLIAM A.. ALLEN, citizens of the United States, residing at Upton, in the county of Siskiyou and State of California, have invented certain new and useful Imrovements in Automatic Distributors for lower-Separators, of which the following is a specification.

Our invention relates to a distributer for what are known as blower-separators for separating sawdust, shavings, &c., from the current of air that is generated by a blower in woodworking shops, as planing-mills, &c. In such devices as now constructed the solid material is apt to pack and fill up the chute and especially if it should be damp, in which case the incoming material is carried out of the separator by the blast of air and deposited on the surrounding property.

The object of our invention is to obviate I these difficulties by arranging an agitator and distributor in the separator, which is adapted to stir the deposited material, and thereby prevent its packing and stopping the discharge-chute and then distribute it within the bin or other receptacle. We prefer to so construct the agitator and distributer that they will be actuated automatically by the current of air from the blower and also to provide them with means to force the material through the chute, if necessary.

An embodiment of our invention is shown in the accompanying drawings, in which- Figure 1 is a broken elevation of a separator and bin-provided with one form of our agitator and distributer. Fig. 2 is a transverse sectional view of the discharge-chute looking down. Fig. 3 is a similar view to show the cut-oif. Fig. 4 is an end view of the cut-off.

Referring more particularly to the drawings, 1 indicates the receiver of the ordinary blower-separator, which is in the form of a casing and located on top of a bin 2 and receives the dust-laden current of air from the blower through a pipe 3. The pipe is arranged tangentially to the upper or cylindrical portion of the receiver or separator, so

that the air on entering is given a rotary moby centrifugal force around the cylinder while the purified air passes out through an opening 4 in the top.

J ournale'd at the upper end of the cylinder is a verticallyarranged shaft 5, which extends down through the separator and the discharge-chute 6 and is journaled in a support 7 above the bottom of the bin. The bearings 8 at the top are adapted to support the weight of the entire apparatus and may be of any desired construction, but is preferably provided with balls 9 and adapted to be supplied with oil to prevent friction. The shaft is also referably made hollow and has its upper en adapted to be connected with a pipe 10, by means of which it can be connected with a water-supply. (Not shown.)

' Rigidly secured to the shaft 5 within the separator, and preferably at or near the top of the hopper portion 11 of the separator, is a frame, which consists of a cross-bar 12 and two wings 13, the latter being secured to the outer ends of the bar and to a block or bracket 14 on the shaft at the bottom, of the hopper. The wings are arranged radially, so as to be acted upon by the lower strata of the rotating body of air, and thereby be carried around in a ra id manner. Where the separator is provi ed with current-interrupters, as blades 15, to intercept the rotary motion of the air and solid material, the lower portion of each wing is notched or recessed and preferably formed from a rod of metal which is bent inward, as at .16,to form a loop for passing over said blades when the wings are rotated;

' Secured to the portion of the shaft 5 that asses down'through the chute, 6 is a forceeed, preferably in the form of a flanged spiral 17, which is adapted to force the sawdust through the chute if it should have a tendency to pack or clog up, as it is very apt to do when damp.

Connected with the lower end of the chute 6 are two conduits, as pipes 18 and 19, one of which, 18, is extended through the side of the bin to the boiler-room in the usual manner, and the other one is more nearly vertical and has itslower end arranged above a distributer. The distributor 1s preferably in the form of arms 20, projecting radially from the shaft 5 above a table or platform 21. A conical shield or deflector 22 is preferably secured to the shaft above the arms,'with its edge secured to the arms at a distance from their ends, so as to throw the material from the spout 19 to the outer ed e of the platform, from which it is thrown by the projectin ends of the arms; said ends bein preferab y curved to the rear, as by making the arms reversely curved, as shown in the drawin s. 1

iocated at the junction of the spouts 18 and 19 with the chute 6 are two valves or cut-ofis, preferably in the form of blades 23, by means of which communication is established between the chute and either one of the spouts, as desired. The blades are referably connected to an L-shaped hand e 24 and are so arranged that when they are re ciprocated they will alternately open and close their respective conduits. The handle is provided with an eye 25 at one end, by means of which it can be reciprocated through a cylindrical bearing 26 to move the blades back and forth. The blades fit within suitable guides, as slots 27, at the upper ends of the spouts, and are connected with the handle in any suitable manner, as by rolling a portion of the end of each around the proper portion of the handle.

Leading from the bottom of the bin is an ordinary spout 28, through which the contents can be removed for use either as fuel or for any other purpose. There is also a waste trough or chute 29 leading from an opening 30 in the bottom of the bin, through which the material in the bin can be removed when there is a su lus. The opening 30 is located directly under the shaft 5, preferably at the center of the bin, so that the sawdust, shavings, 800., will form a fimnel-shaped depression over said opening, as shown at 31, so that when it is desired to discharge any of said material through the waste-chute 29 it is only necessary to pass water down-through the shaft 5, which will fall upon the material and wash it through the o ening into the trough, from whence it can e discharged at any desired oint.

From the oregoing it will be seen that our invention is automatic, yet very simple, and can be quickly and cheaply applied to any of the ordinary blower-separators on the market to-day. All the adjustment that is necessary is to, construct the triangular-shaped agitator to fit the hopper ortion of the separa tor and to provide the ower end of the chute with the form of valve or shut-off that can be operated without interfering with the shaft and its conveyer that passes down between the discharge-spouts.

Owin to the inflammable nature of the materia being handled, precaution must be taken as much as possible to avoid the possibility of starting a fire, as by excessive friction at the bearings or making a spark at any point where the movable arts are liable to come in contact. For this reason the bearings should be ke t well supplied with oil and the platform om which the material is thrown should be made of one kind of metal and the arms from another, as bronze, which will not cause a spark if they should happen to strike while in motion. The hollow construc'tion' of the shaft assists in keeping it and when it is to be stored in the bin it is permitted to fall u on the distributer and is thrown outward y against the Walls of the bin and gradually fills the bin. The distributer is automatically driven at a high rate of speed by the rotary current of air striking against the wings arranged in the' hopper portion of the separator, and in case the material should not pass down through the chute it will be forced through by the rotary screw or conveyer upon the shaft.

Having described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. In a distributer for blower-separators, a casing provided with a chute, two conduits leading from the lower end of the chute, valves for closing said conduits, a rotary shaft through the casing, and a distributer at the lower end of the shaft under the end of one of said conduits.

2. In a distributer for blower-separators, a

casing provided with a chute, two diverging conduits leading from the lower end of the chute,an oscillating valve for each of the conduits, an oscillating handle connected with said valves for moving them across said conduits alternately, a rotary shaft through the chute and between said valves, and a distributer on the shaft below the end of one of said conduits. v
